Description

Computer simulations is a fundamental tool of the design process in many
engineering disciplines including aerospace engineering. However, although
high-fidelity numerical models are accurate, they can be computationally
expensive with evaluation time for a single design as long as hours, days
or even weeks. Simulation-driven design using conventional optimization
techniques may be therefore prohibitive. This book explores the
alternative: performing computationally efficient design using
surrogate-based optimization, where the high-fidelity model is replaced by
its computationally cheap but still reasonably accurate representation: a
surrogate. The emphasis is on physics-based surrogates. Application-wise,
the focus is on aerodynamics and the methods and techniques described in
the book are demonstrated using aerodynamic shape optimization cases.
Applications in other engineering fields are also demonstrated.
State-of-the-art techniques and a depth of coverage never published before
make this a unique and essential book for all researchers working in
aerospace and other engineering areas and dealing with optimization,
computationally expensive design problems, and simulation-driven design.
